Considerations: Students need to be exposed to many ways to represent the unknown (empty box, letters, and symbols). Steps: 1. Listen carefully to the numbers in the word problem. 2. Use the numbers to write an equation using a symbol or letter to represent the unknown. 3. Solve for the unknown.
Application of MPs: MP2: What math symbol can you use today? MP6: How do you know your answers are correct? MP7: What steps help you solve the problems?
